I did an electroporator design up to the testing stage with funding from 6 kickstarter backers and $2k from Bryan Bishop.
It's open hardware published on github at https://github.com/kanzure/culture_shock.

It is physically in only two prototypes, I have one and Nathan McCorkle has one.  The six kickstarter backers would not contribute
any time testing and it stalled out for lack of a complete enclosure -- it needed a laptop just to turn on -- no buttons for setup
and fire...

So, I worked for 6 months for $3k and didn't get to a viable product.  Case study complete.

Now aiming at RV solar PV battery appliance designs like:  on demand teapot, DC microwave oven, DC refrigerators, etc where the
wiring between solar PV panel and battery bank is small gauge, easy to wire into a house, easy to repair, and the controller
manages batteries of most any kind individually so the user can change them out by messages like "replace cell D8",  "cell B3 now
has 2 Ampere hours, half its original capacity".

Now I'm not planning to release any of those until having a good way to make plastic moldings in 100's.  So I'm designing molding
equipment also.   The 3DP machines have matured and many are available for cheap, so maybe I'll use some of that for enclosure
production, but still thinking it will be by 3D printed MOLDS filled by low pressure injection of thermoplastic and with fairly
visible mold parting lines done slowly, automated, so the temperatures of the mold go up and down for molding and release.  It
needs a cheap automated part eject/remove/stack robot also.  Anyone heard of progress along those lines so I could buy small
plastic moldings in the 100's for about a dollar a piece, instead of make?
